How to get a redistributable copy of "Microcode (0x129) Update for Intel Core 13th and 14th Gen Desktop Processors"?

In #78 it was argued that the elevated-voltage related update won't be distributed via this repository to avoid confusion (as it can't be applied from the OS). However, independent manufacturers and firmware vendors rely on redistributable binaries (as they are licensed in this repository) when they don't work very close to Intel. Especially when open-source firmware is involved that sometimes even the customers compile themselves, the chain becomes too long to sign an NDA for every single case.

How can we get redistributable binaries for such not-OS-applicable updates into the ecosystem?
